BS 4651-3:1987, ISO 7109-1985

Overview

BS 4651-3:1987, aligned with ISO 7109:1985, provides a standardised method for determining the residue on evaporation of ammonia solutions. This standard is crucial for laboratories and industries that handle ammonia solutions, ensuring consistency and reliability in testing procedures. The determination of residue is vital for assessing the purity and quality of ammonia solutions, which are widely used in various chemical processes.

Key Requirements

The standard outlines specific requirements and procedures for the evaporation method, which include:

• Sample Preparation: Proper sampling techniques must be employed to ensure representative samples of the ammonia solution are obtained.
• Evaporation Procedure: Detailed steps for the evaporation process are provided, including temperature control and equipment specifications.
• Residue Measurement: Guidelines for accurately measuring the residue left after evaporation, ensuring precision in results.
• Reporting Results: Standards for documenting and reporting findings, which are essential for compliance and quality assurance.

Implementation Benefits

Adopting BS 4651-3:1987 offers several practical benefits for laboratories and manufacturers:

• Consistency: The standard provides a uniform method for testing, which enhances the reliability of results across different laboratories and batches.
• Quality Control: Regular adherence to this standard aids in maintaining high-quality ammonia solutions, which is critical for various applications, including agriculture and chemical manufacturing.
• Regulatory Compliance: Following this standard helps organisations meet regulatory requirements, reducing the risk of non-compliance penalties.
• Improved Efficiency: Streamlined procedures outlined in the standard can lead to time savings and reduced operational costs in testing processes.

Compliance Value

Compliance with BS 4651-3:1987 is essential for organisations that produce or utilise ammonia solutions. By adhering to this standard, companies can:

• Enhance Credibility: Demonstrating compliance with recognised standards builds trust with customers and stakeholders.
• Facilitate Trade: Compliance can ease the process of exporting products, as many international markets require adherence to specific standards.
• Mitigate Risks: Regular testing and adherence to standards help identify potential issues early, reducing the risk of product recalls or safety incidents.
